Louis van Gaal saw his side finish fourth in the 2014/15 season as the Blues went on to win the title comfortably. At Real Madrid, the Welsh international struggled to replicate his first year's form last term.

United were interested in signing Bale before he left Tottenham for Real in 2013. The 20-times English champions are still keen on landing him in the summer transfer window, despite his desire to continue at the Spanish capital club.

Redknapp believes Bale can help the Red Devils bolster their attacking division for the next season.

"Absolutely [Bale can help United win the title]. If you said to me, as a Premier League manager you could have the pick of one player in the world, it would be Gareth above any other player - if he wanted to come back," Redknapp explained.

"A year ago, for me, he was the third best player in the world. He maybe has fallen behind Neymar and Luis Suarez now but he could come back here, as a fantastic footballer, and if he came back to England he could change the fortunes of a football club - he has that much ability."

Bale has been constantly criticised by a large section of Real fans, which has seen him being linked with a move away from his current employers. However, the former Tottenham star has stressed that he is willing to continue with the La Liga giants and prove his worth.

Redknapp has advised Bale to return to England, as he believed the Wales international can be the best player in the Premier League.

"He is a fantastic player, if he came back he'd be the best player in the Premier League by a mile," the former Tottenham manager said.

"He is a good lad and an amazing player. He can terrorise teams on his own. You saw what he did at Tottenham, the games that he won almost single-handedly. Almost every other week there was a last minute goal from Gareth."

"He is an amazing talent, he can score goals, he can make goals, he can run, he can dribble, he can shoot," Redknapp concluded.
